Warning Lamps
Malfunction Indicator Lamp If it illuminates when the engine is
running, the on-board diagnostics
system is detecting a malfunction
of the vehicle emission control system.
If it flashes, engine misfire could be
occurring. Increased exhaust gas
temperatures could damage the catalytic
converter or other vehicle components.
Avoid heavy acceleration and deceleration,
and have your vehicle checked as soon as
possible. Powertrain Warning Lamp If it illuminates when the engine is
running, this indicates a powertrain
or four-wheel drive fault. If it
flashes when you are driving, immediately
reduce the vehicle speed. Avoid heavy
acceleration and deceleration, and have your
vehicle checked as soon as possible.
If both lamps illuminate when the engine is
running, stop your vehicle as soon as it is
safe to do so. Continuing to drive your
vehicle could cause reduced power or the
engine to stop. Switch the ignition off and
attempt to restart the engine. Have your
vehicle checked as soon as possible.

WHAT IS THE CATALYTIC
CONVERTER
The catalytic converter is part of your
vehicle's emissions system and filters harmful
pollutants from the exhaust gas.
CATALYTIC CONVERTER
PRECAUTIONS
WARNING: Do not park, idle or drive
your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is very
high. Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short period
of engine operation and stays hot after the
engine is switched off.
To avoid damaging the catalytic converter:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables.
See Jump
Starting Precautions (page 309).
• Use the correct fuel.
See Fuel and
Refueling (page 197).
• Do not switch the ignition off when your
vehicle is moving. •
Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Do not make any unauthorized
changes to your vehicle or engine. By law,
vehicle owners and anyone who
manufactures, repairs, or services a fleet of
vehicles are not permitted to intentionally
remove an emission control device or
prevent it from working.
CATALYTIC CONVERTER –
TROUBLESHOOTING
Catalytic Converter – Warning Lamps
Your vehicle has an on-board diagnostics
system that monitors the emission control
system. If any of the following warning lamps
illuminate, this may indicate that the on-board
diagnostics system has detected an emission
control system malfunction.

Continuing to drive your vehicle may cause
reduced power or the engine to stop. Failure
to respond to a warning lamp may cause
damage that your vehicle Warranty may not
cover. Have your vehicle checked as soon
as possible.
